Answer.
The answers is A; The physical and chemical properties of HCl are different from those of H2 and Cl2.
Explanation;
Hydrogen chloride is a gas, which is a molecule made up of a hydrogen and a chlorine atom bonded by a single bond.
The chemical and physical properties of HCl differs from those of hydrogen and chlorine. For example; they have different molecular weight; HCl is colorless, while chlorine is greenish yellow and hydrogen is colorless

Answer:
The correct answer is <em>They move through an electron transport chain to Photosystem I.</em>
Explanation:
Luminous energy is trapped by a chlorophyll molecule in the <u>Photosystem II</u>. When the pigment molecules absorb light, electrons get in a higher energy level. These excited electrons go through the electron transport chain to an inferior energy level in the <u>photosystem I</u>. When the excited electrons leave photosystem II, they are replaced by new electrons that are extracted from the water molecules. As electrons go through the transport chain, their released energy is used to <u>produce ATP molecules</u>. Luminous energy absorbed in the photosystem I move the electrons to another electron acceptor from where they are transported again and used to produce NADPH molecules. When electrons are eliminated from Photosystem I, they are replaced by new electrons that are coming from the photosystem II through the transport chain.
